One of the more heated rivalries on ice is coming to the curling sheet. Canada and the United States, longtime foes in hockey, will clash in the Olympic men’s curling semifinals Thursday at 6 a.m. ET, with a chance to play for gold on the line.

It was their dream — all four members of Rachel Homan's rink — to curl for Canada at the Olympics and bring home a medal, shedding tears of joy after qualifying. But when their hopes of a curling medal were dashed in a loss to Great Britain, there were different tears.

After a fourth loss in the Olympic women's curling tournament on Tuesday, Rachel Homan must win her final two round-robin games or else become the first Canadian skip to miss the medal round. Standing in her way is a team coached by a Canadian curling legend.

A loss to Sweden, no problem. A loss to Switzerland, no panic. But a loss to the United States, the third consecutive defeat for Kevin Koe and his team out of Calgary, and now there's a serious sense of urgency at the men's curling tournament in Pyeongchang, South Korea.

After their shocking 0-3 start to the Olympics, Canadian skip Rachel Homan and her teammates went behind closed doors for a heart-to-heart, then looked like a new team in Saturday's much-needed 11-3 trouncing of the United States.

Niklas Edin curled a near-perfect game against Canada as Sweden stole three points in the match to beat the three-time defending Olympic champions 5-2 at the Winter Olympics in Pyeongchang, South Korea.

Fred Koe fell in love with curling before he was ripped from his home and placed in a residential school in the Northwest Territories for 10 months. When he had his own family, he used his favourite sport as a way to stay connected with his three children — including a son who is now Team Canada's skip at the Olympics.
